In recent years, robots are not only used in industry, agriculture and other fields, but also increasingly widely used in the medical field, and have become the focus of the medical industry. At present, the field of surgical robots mainly includes orthopedic surgical robots, neurosurgical robots, vascular intervention robots, laparoscopic surgical robots, and so on.

The traditional surgical operation is that doctors use medical instruments to remove and suture the body lesions of patients. Use knives, scissors, needles and other instruments to operate locally in the human body to remove diseased tissue, repair damage, transplant organs, improve function and shape, etc. Accurate and minimally invasive surgery has become the goal of current surgery. With the development of surgical robot technology, even in complex surgical scenes, with the cooperation of doctors, surgical robots can also complete tasks.

What advantages does orthopedic surgery robot have compared with traditional surgery?

Compared with traditional surgery, orthopedic surgery robot assisted minimally invasive surgery has obvious advantages:

Small surgical wound, fast postoperative recovery and less postoperative complications

Compared with the large incision of traditional surgery, the surgical robot usually has only a small number of small incisions in the robot micro-trauma surgery, and the incisions are used to put surgical instruments, so the orthopedic surgical robot can complete in the way of precise micro-trauma. This will also significantly reduce the risk of blood loss and postoperative complications, such as infection and adhesion, so that patients can recover faster.

Flexible manipulator is compatible with highly complex surgery

Orthopedic surgical robots are usually equipped with one or more manipulators with high degrees of freedom. Through computer algorithm processing, the mechanical arm copies the activities of the surgeon's hands into the corresponding instrument movements in the human body. This enables surgeons to move surgical instruments smoothly and accurately in a small operating space, which is indispensable in highly difficult surgery.

Accuracy and stability of surgery

For example, in orthopedic surgery assisted by orthopedic surgery robots, doctors scan the 3D human body information of patients into the computer through fluoroscopy or scanning. After the automatic matching is completed, the patient's bone tissue can be seen, and the doctor can choose the appropriate path to avoid the important tissue parts of the patient. After confirming the surgical path, the robot can move to this place accurately through navigation technology and robot arm motion control technology, with accuracy error of sub-millimeter level.

In addition, orthopedic surgical robots give doctors more flexible hands, and automatically filter the intrinsic tremor of surgeons' hands through computer algorithms. It reduces the risk of accidentally cutting tissue, and greatly improves the accuracy and quality of surgery.

Reduce radiation exposure

In some open surgery and traditional minimally invasive surgery, surgeons must obtain a series of X-ray films to confirm that the implants are placed in the correct position. The orthopedic surgical robot is generally equipped with an optical navigation system that can indicate the placement position of the implant, which can greatly reduce the number of X-ray films required in surgery. This will reduce the radiation exposure of surgeons, patients and other operating room staff.
